I thought it to be correct because sqrt is the opposite of multiply by a number, so ns figured by multiply by a number it would certainly balance out and also be that number normally, but when ns tried it v my Python calculator using 3 ns got:

civicpride-kusatsu.net.sqrt(3) * 3 5.196152422706632



$\begingroup$ $\sqrt x$ is the number to solve $\sqrt x \sqrt x = x$; it's no the the opposite of multiplying by $x$. $\endgroup$
In general, no. Because $\sqrt x$ is equal to $x^1/2$, your equation is the very same as $x^3/2 = x$, only $x = 0, 1$ work-related as solutions


If you want to solve because that the equation$$x\sqrtx = x$$then girlfriend have$$x (\sqrtx-1) =0 \Rightarrow x = 0, \text or \sqrtx=1, \text i.e. x = 1$$


The multiplicative train station (the "opposite" in your question) the a non-zero number $x$ is that is reciprocal, $\frac1x$. Multiply these two together provides instead $x \times \frac1x = 1$.
